• Error code 646 when trying to install Windows updates.

  Windows updates appear to download but will not be installed.  I tried to go into 'control panel '; Security systems &; then Windows updates.  It checks and concludes that they are downloaded and try to install but won't.   My computer is set to automatically download and install, so I'm never checked to see if they really were the installation so far.  It seems the latest installations of updates took place the 1/11 & 12/01/11.  There has been many failures last year.  Right now, it seems that there are 6 updates important and 6 optional updates that will not be installed.

  I tried to disable my Norton Internet Security and then the installation, but that does not work either.

  Can anyone help?

  Thank you.

• Receive error 646 when attempt to install automatic updates

  several updates fail to install automatically and are listed as having failed in the update error code 646 story but when I manually install they go on the list of installed updates and if I try to reinstall I get the message that they are already on the system, but still they show as failed in the action center of windows and on the history of updates list. Who is this. they are there or not? I ran a windows Cleanup. tried to remove and reinstall, reboot. I always get the message failed. It's 979441 and 982331. I had problems with the automatic updates before but were able to install and get the deleted manually failure message. I was told this morning when I tried to manually reinstall I did not require 2331 441 and it was already there.

  Hello

  Here's what I recommend you do:

  1 disable UAC. Down comes the restrictions - turn it off completely.
  2 restart your computer for the change to take effect.
  3 re - download the update of security for Microsoft Office System 2007 (KB982331) from the link below:
  http://www.Microsoft.com/downloads/details.aspx?FamilyId=7f89a734-cda4-4abb-9a10-f6dfe560e8d0&displaylang=en
  4. install. It should work fine.
  5. If it still does not work, try to open all or part of your MS Office applications (such as MS Word, MS Excel, etc.).
  6. follow steps 3-4.
  7. If it still does not work, follow step # 3 again. After you download it, try to disconnect your computer from the internet (unplug the internet cable or turn off the modem). Then, try to install the downloaded (KB982331). It should work this time.

  Let me know your results.

• Cannot get beyond error 0x8024D007 when trying to get Windows Update or Microsoft Update

  I tried to get the Windows Update and Microsoft Update on a Windows XP computer as well, but I got the error 0x8024D007 with both.  In view of this error message on your site, I did the registry fix and still no change.

  It took me awhile, but I found a solution that worked for me.

  1. Remove Service Pack 3 - if in Control Panel , you do not have an option delete, just Start, run and type: c:\windows\$NtServicePackUninstall$\spuninst\spuninst.exe

  After removing SP3 restart. Now, go to Windows Update and it should load fine. Go ahead and install high priority updates and reboot again.

  2. reinstall Service Pack 3 - it is better to just download the .exe for SP3 file and run it from the machine rather than using Windows Update to download and install. Before you try to run the .exe however, go ahead and avoid the "Access denied" error by typing this command in a command prompt window:

  secedit/configure /cfg %windir%\repair\secsetup.inf /db secsetup.sdb/verbose (Pay attention to the spaces)

  Now you can reinstall the SP3 and Windows Update should work again. If you get hooked to the last part of the installation which is "Scene cleanup", make sure that you have given him enough time to finish (a few hours) then simply open the the Task Manager and end of the process. Reboot, and you're good to go.

  * This fix also worked on a Server 2003 that had the same problem. Uninstalled and reinstalled SP2 using the same method. It is now up and running and pulling on the updates.
